You could just come to eastern South Dakota anytime between March and May. And shoot as many as you want. I could let you know how the migration is going when it gets closer. Pretty much any farmer will let you on his land to hunt them.

Okay the snow geese are starting to come into the state. So if you plan on coming this next week will be the best since spring break starts and there will be less pressure. There should be huntable numbers too by then.
